South Arkansas: Eight out of the nine RRVP fields in the south are planted and those emerged have excellent stand counts. More rain this past week was the topic of discussion with amounts ranging from 3.75’ in Lee and Monroe Counties to 2.75 in Desha and Chicot Counties. While the rain has hampered planting it has been good for continual pre-emergence herbicide activity. The Jefferson and Lincoln County row water fields received Prowl H2O this past week. The Monroe County Prowl application should go out this morning 5/9. The rainfall expected today with the off and on showers predicted this week should add to more residual grass control. The Arkansas County field received a Facet application to hopefully take us to flood, weather permitting. The DD-50 from the multiplier field in Arkansas County is calling for the single pre-flood N-STaR fertilizer application to go out this morning. Hopefully the fertilizer is able to go out on dry ground prior to the rain.
North Arkansas: White County was planted over the weekend bringing the current total in north Arkansas to seven. Cool nights have noticeably slowed seedling growth in emerged fields this past week. Two fields, Mississippi and Clay Counties, have sustained injury from herbicide drift (also some stand loss in Mississippi) but are producing new growth and are expected to recover significantly by the end of this week. A third field, Conway County, did not emerge as well as projected and is also a little short of the desired stand. Ammonium Sulfate was applied in all three of these fields over the weekend to help boost the growth of the rice and more rapidly achieve tillering where stands are somewhat thin. Three fields received a post-emergence herbicide application: Jackson County (Newpath), Cross County (Obey + Permit), and Lawrence County (Newpath + Strada).
